To delete a SPAN session, use the no monitor session session_number global configuration command.
To remove a destination port from the SPAN session, use the no monitor session session_number
destination interface interface-id global configuration command. To remove the RSPAN VLAN from
the session, use the no monitor session session_number source remote vlan vlan-id.
This example shows how to configure VLAN 901 as the source remote VLAN and port 1 as the
destination interface:
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface gigabitethernet0/1
Switch(config)# end
Creating an RSPAN Destination Session and Configuring Incoming Traffic
Beginning in privileged EXEC mode, follow these steps to create an RSPAN destination session, to
specify the source RSPAN VLAN and the destination port, and to enable incoming traffic on the
destination port for a network security device (such as a Cisco IDS Sensor Appliance).

Purpose
Specify the RSPAN session and the source RSPAN VLAN.
For session_number, the range is 1 to 66.
For vlan-id, specify the source RSPAN VLAN to monitor.
Specify the RSPAN session and the destination interface.
For session_number, enter the number defined in Step 6.
In an RSPAN destination session, you must use the same session
number for the source RSPAN VLAN and the destination port.
For interface-id, specify the destination interface. The destination
interface must be a physical interface.
Though visible in the command-line help string, encapsulation
replicate is not supported for RSPAN. The original VLAN ID is
overwritten by the RSPAN VLAN ID, and all packets appear on the
destination port as untagged.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
